Henry Shires has just introduced the Notch Li gen. 2 solo tent. Take a look on his website.
The upgrades are waterproof 2-way zippers and a lighter "solid" inner tent.
Being a hiking pole supported tent requires you take least 4 stakes, 2 for the ends and 2 for the sides. Take 2 more stakes to guy it out at each side for windy conditions.
For my aging body I "need" this tent and will likely get it this month (April, 2020) for this summer's trips.
Along with a lighter mattress (REI FLASH Insulated Regular at 15 oz.) and an Osprey EXOS 58 pack, carbon fiber hiking poles, TD Sidewinder ti Caldera Cone stove for ESBIT tab fuel and a few other light items I think I can backpack for 5 days with a 25 lb. pack. That's UL but certainly not SUL. I value comfort, both on the trail and especially at night.
Since moving to Nevada in 2004 and finding good backpacking sites like Trailspace I've cut my 3 season pack weight by at least 20 pounds! It really makes a difference to this geezer.
I do credit advances like carbon fiber hiking poles, Dyneema packs and tents, lighter mattresses, stoves, etc. for this weight reduction as well.
